3Vertex Maximum or minimum of the graph For the equation, the vertex is at
4Identify the vertex for each function 1. f(x) = | 2x – 5 |2. f(x) = | 3x + 6 |3. f(x) = - |x + 1 | - 2
5Graphing absolute value functions by making a table Find the vertexMake a table of values (at least 5!)Graph the function.
6Find several ordered pairs for each function. Graph and on the same coordinate plane. Determine the similarities and differences in the two graphs.Find several ordered pairs for each function.x| x – 3 |31245x| x + 2 |–42–31–2–13Example 6-3a
7Graph the points and connect them. Answer:The domain of both graphs is all real numbers.The range of both graphs isThe graphs have the same shape, but different x-intercepts.The graph of g (x) is the graph of f (x) translated left 5 units.Example 6-3b
